A control circuit generates two sorts of printing timing signals on the basis of the position of the printing mechanism module detected by a detector, and sends the generated signals to respective drive circuits. Herein, the printing mechanism module is configured of two printing element assemblies each of which includes a plurality of printing elements, and both of which are mechanically coupled. The two drive circuits taking charge of the two printing element assemblies send printing input signals to the respective printing elements which are to be driven according to the two sorts of printing timing signals received by the drive circuits. The relative positions between the print dots of the two printing element assemblies can be adjusted for each direction of printing on a sheet by changing the difference between the times of the two sorts of printing timing signals.
